Keep your transmission fluid and gear lube where it belongs with our Aluminum Foamet Material (AFM) Gaskets. AFM consists of an aluminum core and features a foam rubber coating bonded to both sides. Ideal for sealing less than perfect surfaces and can be installed without the use of additional sealers!
